Topic: Wal-Mart Battery - field problems

[willndmb]

Just to chime in again, I keep my pre plugged in to the power "harnes" at all times, plug the battery in, then turn on the pre.  It's possible that when I had my problem I somehow had the pre power button "on" .

this is what i do, the cable is plugged into the pre 100% of the time
and then i plug the cable into the battery and turn the pre on
i am using a bumblebee vr box, but tripping the battery should be the same no matter what you use for a cable

I got a new pair of these Li-ion 9V rechargeables to maybe replace the 2-9V alkaline power supply I use to power my NAK MX-100 mixer.  Gonna hack the cables tomorrow and solder the ends into a 4-pin female mic connector, like the 2 alkalines are setup now.  There's no power switch on the mixer, so I'll be plugging in hot ---- hope the current surge doesn't pop the protection circuit, or else I'll be back to using alkalines again.  I suppose one could make up a 12V sled of AAA batteries to jumpstart a Li-ion, though.........it would save having to search around for AC.  I'll let you know if this works for me......

Wow - that ought to last awhile...!

I was wondering if there was a way to pull it off using 1 Wally 9v - and some sort voltage splitter/divider?

The MX100 does suck down the 9v snap ons - I feel like I have to use a new set every show...

Yeah, I used to have a great source for Heavy Duty 9Vs at the indian reservation near here ------- $0.49 for a pair.  I would just run them one show, and give them away to people afterward.

Think the 12V bump sled would work to reset the Li-ions?

I keep my cable plugged into the pre and the battery at all times.  Does this drain the battery down even if the pre isn't on?  Should I not do that?

I wish I had a picture, but I took a 9v battery and wired a plug that fits into the "charger" jack on my LiOn's. It works like a charm to get them going again when they shut down. I have found that they shut down when hit with a big load or a direct short. The 9v battery trick works in the field, when you don't have an AC outlet to use. I have also thought about just making a jumper between the two LiOn's I have. That way I could use one battery to re-start the other, but more important and useful, I would be able to keep one going if the other is getting depleted by passing the 9v from the good one into the "charger" jack of the depleted one.

Good one, Chuck!  Nice to know a 9V will reset it.........+t

Can you simultaneously charge and use the Wally batteries this way?  Can you have the AC adapter plugged in and still get power out?

No, doesn't work.  As soon as you plug in the charger, it shuts off the regulated output from the battery pack.

Oh, well...
